Aona brought Fang Zhu to a corner of the room, but she didn't see any movement. The bookshelf there quietly slid to one side to reveal the stairs that rotated upwards behind. She turned around and reminded her carefully: "Above this, Mr. Ed, please pay attention to the light inside. Sorry, I haven't been here for some time. Why don't Pepe go up and light the light first?"

"No need." Fang Yu shook his head. He didn't want to waste time. There was no need to worry outside. He had already told others that there were Miss May, Xie Shita and Luo Yu were enough to stand alone here.

Even if there was an emergency, he left a flexible configuration of his own. Fang Yu raised his head and looked at the deep ladder, "Is this above?"

"It's just an attic, and it's all filled with things from the past. I remember putting that letter here, which was already the thing before Castana was abandoned. By the way, that's the name here, including the ruins above, Mr. Ota should have told you."

Aona walked into the secret passage first, walked in front, and walked up the steps step by step. She was not physical, but the projector could still accurately reflect the girl's shadow step by step.

The fluorescent blue light shines the inner wall of the secret passage, and the fine rocks come from the artificially polished rock walls.

She said as she walked, "But that's fine. Otherwise, we'll have to go to other places to get it. Although I remember every secret room underground, those places are quite far away."

The girl recalled: "A long time ago, I would occasionally come here alone, look at things and recall the past. I remember that the study room of Haylinwell and others was once on the spot. They would often light up the fireplace and talk at night, telling some strange scenery and stories from all over the place. The fire was bright and illuminating the faces of each of us. At the beginning, they spent a lot of effort to design the fireplace in the cave. There was actually a huge machine in the chimney, and the fireplace in the hall downstairs was the same, but that was the subsequent version. I can still remember everything at that time, short, simple but happy..."

Aona seemed to untied a knot in her heart and became a little chatty. Pepe took the necklace and followed behind them.

Through her words, Fang Rong seemed to be able to see clearly what happened seven hundred years ago. Three young people came here and dug out the gem with a bright green light from the soil.

He built a laboratory based on his own ideas, avoiding the pursuit of the empire, while talking about the future and making grand plans.

Young people have countless energy and enthusiasm, and design one device after another in this dark underground that is enough to change the future of this continent. But in the darkness, there is only the lush light emitted from the crystal, swaying, reflecting everyone's heart.

After that, the land of Xinta Ankong changed, a dynasty collapsed, and an empire was established, but ideals were dispersed and only ambition was left. Within a hundred and ten years, many people came here and built an underground city.

Aona, and a huge and lonely iron statue of Ota, Pepe's ancestors were watching those people in the dark, not making much contact with them, but providing help in the dark.

She had thought about revenge, but the fiery flames in her heart had long been worn out with time, and even the descendants of the Helinwell students gradually decreased. This dark underground that had been silent for millions of years returned to silence after a brief hustle and bustle.

It is hard for Fang Yu to imagine what kind of loneliness it was.

A door appeared in front of the two of them, and the thoughts disappeared in an instant. The stone steps were not too long. The square leopard felt that this place should be roughly above the hall below based on its sense of direction.

The door looked thick and had iron frames on the solid wooden boards. Such wooden doors were common in some castles, probably imitating a similar room on the ground.

The builders deliberately downplayed the underground factors here, and it can be seen that the three geniuses are all people who have certain pursuits for life. They transformed the arduous environment here, but they could still enjoy the hardships.

Aona asked Pepe to open the door, and the puppy man walked over and tiptoed to grab the door handle.

But before the door opened, Fang Zhu asked a question: "Ms. Aona, where did the students of Helinwell go to the end? I saw that Castana had turned into ruins. Those people should not die with the city, right?"

He still cares about the knowledge temple under the remains of the elves. Has the great alchemist Hein visited Korlin-Ishurien in the last decade of his disappearance? Zero Magic was born in the hands of his student Helinwell. So does Helinwell know about the existence of Zero Crystal?

Has Helinwell tried to find the whereabouts of his mentor and the whereabouts of the Crystal of the Switch Crystal? He did not return to this place in the end, where would he have to go for the rest of his life?

Will the students of Helinwell know something about this? Is there any word of information that leaves anything in the inheritance of this lineage? Can he find successors of the Sixth Technical Route elsewhere or clues they leave behind?

"Some people left, some people stayed, but humans were not creatures living under the darkness. I don't know how many years have passed, and the empire outside can no longer remember such a group of people, and fewer and fewer people left behind. Finally, they gathered in the church you once entered, and that was the last one who stayed."

Aona turned around and replied in a quiet tone: "When those people passed away, this place changed back to what it was a thousand years ago. The city was weathered in time, covered with thick dust, and cracks were produced, eventually collapsed and turned into ruins. But I didn't use that big place, just living alone here."

This chapter is not over, please click on the next page to continue reading! Pepe fiddled with his claws several times, and finally pulled down the door handle with a "click". It pushed it hard, but the door did not move at all. Fang Zhu reached out to his hand when he saw this, and then pushed the door open a gap.

It was probably not a long time since anyone moved it, and the door shaft had already rusted and made a squeaking sound. The dog-headed man turned around and looked at him with some gratitude, but Aona did not allow it to talk too much, so Pepe had to obediently not say a word.

Fang Yu pushed open the door and realized why Aona said that this was a loft. He really underestimated the peerless genius seven centuries ago. A certain spell was constant in the room, and there was a floating starry sky on the ceiling.

To be honest, he had seen similar spells in the Thousand Gate Hall, but he had never seen such a gorgeous one. The blue starry sky completely formed the roof of the attic, and the twinkling starlight seemed to be within reach with just a slight stretch of hand.

There was a sofa in the room facing a fireplace. The flames in the fireplace had been extinguished for many years, and a thick layer of gray was accumulated on the carpet in front of the sofa.

Perhaps many years ago, there were several pairs of boots walking around this carpet, and their owners were all amazing people of that era, but such imaginations reflected the silence at this moment.

Next to it is a bed and a desk. The books on the desk are erected and neatly scribbled. One of them is spread out on the table, as if someone had just flipped it up not long ago. There is an ink bottle next to the book and a quill is inserted inside. If it weren't for the thick layer of dust on it, it would have almost made people suspect that someone had lived here.

But it's just time that solidifies everything.

There is actually a floor-to-ceiling window next to the bed.

Just like the arch windows on all the attics in imperial style buildings, they are tall and transparent, and the silver moonlight shines on the bed, leaving a pool of clear light.

If it weren't for knowing that the window was under the rock formation, Fang Zhu would have almost suspected that the window led to another world, perhaps it was Aiyin Bullock seven hundred years ago, or a street in the imperial capital, with moonlight shining on the dense roofs, a piece of tiles blue or gray-brown.

The lights swayed under the night, and the text was obviously silent.

Fang Yu was stunned for a moment. No wonder Aona liked this place. This must be a place that the three geniuses attached great importance to, so it was transformed into this.

This place might be her dormitory, the room of a princess of the last dynasty. Several young people often gather here to share their stories with each other. Some of those young people might have loved this princess.

"Make Mr. Ed laughing," Aona said, "that letter should be stored in a pile of debris here. I will take Pepe to find it. Please, Mr. Ed, go and turn on the light."

Fang Yu nodded. His eyes swung across the room, looking for the location of the torch stand or crystal lamp, while imagining what the room meant to those peerless geniuses.

But he suddenly saw a huge machine in the corner of the room, like a huge magic furnace, with countless pipe networks extending from the floor and ceiling, connected to the appliance.

The magic weapon has an octahedral square cone shape and is inserted on the base below. Many metal wrists hang down from above and scattered all over the ground, with objects like claws connected to the other end.

Fang Yu had never seen such a weird magic weapon. It looked like an enlarged version of the Annihilation QV700, but it also seemed to be the core of something. He couldn't help but take a look and asked, "Is this?"

"One of Gerdham's inventions," Aona's eyes flashed and she replied, "If Mr. Ed is interested, you can study it later."

Fang Yu glanced at the thing again and nodded, but he always felt that the thing was a little unsafe and did not get too close. Instead, he walked over the metal wrists on the ground towards the fireplace.

He couldn't find where the magic light switch was, but suddenly he had an idea.

There was some firewood piled beside the fireplace. The air here was very dry. Fang Zhu felt that he might be able to use the fireplace to light it up.

But a crisp sound of "click" came from behind him, and the square rooster did not look back. A bright blue light lit up from the magic furnace behind him, forming a dense mesh structure.

The translucent light net lit up, and another metal crossbow hit the top, turned to the side, hit the stone wall of the fireplace, and then lost its strength and fell to the ground.

Fang Yu glanced at the crossbow arrows that had cracked the arrows on the ground, then turned around and looked at Aona not far away with a quiet look. The jade necklace had flew up from Pepe's hand at some point, and an invisible force controlled it to fly to the machine in the corner of the wall.

The girl raised her hand and pressed the pendant against a groove on the machine. On the other side, a crossbow that had turned out from there was floating at her hand.

The bow string has been reset, and the crossbow arrows on it have long disappeared.

"The energy shield of the magic furnace," Aona looked at Fang Ling in surprise, "Mr. Ed, have you been guarding against me for a long time?"

"You know even this. Miss Aona seems to know much more about the world on the ground than I imagined," Fang Yu said, "There was no small shield on the magic furnace earlier. It was invented in the era after the tower magic furnace."

Aona's expression was a little stiff, "Mr. Ed doesn't need to slander me. You are not from the imperial family. You have helped me a lot. I had no reason to be enemies with you. But you have something to do with that person, so I can't let you leave easily."

"That person?"

Fang Yu was stunned.

His defense against the other party comes from many aspects, the main reason is the tower magic furnace and the prompts Silweid gave him. After many temptations, the other party failed to pass.

Aona said she did not understand alchemy and had little understanding of the mechanisms left by Gerdham, Helinwell and Friston back then. It turned out that this was not the case. Others may not have noticed it, but he believed that Xiaoyao, Shui Wuming and Luo Wei must have noticed it just like him.

This chapter is not over, please click on the next page to continue reading! Perhaps because he was too anxious about the necklace, Aona herself did not notice that she revealed too many things when discussing the three mechanisms with them. It is impossible for a person who is completely ignorant of alchemy to understand those things.

Besides, she has been with Helinwell's students for quite some time, and alchemy may be complicated, but after hundreds of years of accumulation, she will more or less master a lot of knowledge. Then there must be a reason for this woman to lie to them.

From then on, he had already laid his guard down.

However, if you want to talk about the real suspicion, it was the jade necklace. At first he thought it was the jade heart, but after testing it with Cang Zhihui, he did not respond, but he discovered the real secret inside.

The necklace was a key, which was very similar to the one left to them by the guy who claimed to be the pirate king.

Regardless of the key to open, it at least proved that Aona did not tell them the truth. The pendant was not a memorial at all, but something she had other intentions.

Therefore, when the other party invited him to get the letter, he was careful and quietly turned on the spare shield of the magic furnace, he also left a flexible configuration in the hall.

And leave a message to Rowe and Silweid.

He came here because there were too many puzzles in his mind that he had not solved. Who was Aona and what was she trying to do? Where did Helinwell, Gerdham and Friston go in the end.

She might know that she just didn't tell the truth. Helinwell's student could never come here to take refuge, because he himself was the inheritor of the Sixth Technical Route and naturally understood the attitude of the craftsmen towards the ideals they had pursued throughout their lives.

In short, too many questions need to be answered.

And now, he got the first answer.

That is what key is that necklace?

The jade pendant sank slightly in the sank of the structure. Aona looked at him angrily, "Prepare less garlic and hand over the mechanical soul! Otherwise, no matter how many times you are resurrected, I will definitely chase you to the ends of the world!"

Fang Yu was shocked.

He thought about many aspects of what the girl in front of him invited them here, but it was definitely not for opening the box, which should be an unexpected surprise for the other party.

It was in that ruin that she saw what characteristics of them through Ota that set up a trap for them to come to this place. Fang Yu believed that if they hadn't offered to try to unlock those three mechanisms, the other party would have taken action against them long ago.

At first he thought about the Zero Magic Fire. Aona should be interested in the Zero Crystal on him. This logic is very smooth and it is the only thing he thinks he has a connection with this place.

But just before entering the door, he took the initiative to ask questions about the church. The other party seemed to know nothing about the secret behind the statue of Angine, which also dispelled his original idea.

But unexpectedly, Aona surprised him as soon as she spoke.

His first thought was that the other party discovered the truth about Miss Dragon Soul on his body.

The second idea is that the Tower of Silver is actually involved in this incident.

But time has no longer allowed him to have a third idea, because the huge machine beside Aona has made a squeaking sound, as if awakened from the dust of history.

Its shell slowly opened and then rose from the base, combining the projector above Aona's head like a deformation, and then the internal mechanism was running, hinging the two little by little.

Aona's image was a little unstable, and her voice was intermittent: "Didn't you ask where my body is? Now... you see..."

She raised her hand.

The octahedral square cone magic weapon suddenly turned around, and the crystal embedded on it lit up slightly, and a dazzling red light flashed. Then, under the guidance of the girl, the metal wrists connected around it came alive.
To be continued...
